"Joint account" between whom? Father and mother? Father and daughter? All 3? It it was a joint account of father and mother, it now belongs to mother. Power of attorney usually does not include power to make gifts or power to make a will. When mother dies, the power of attorney will expire. Anything left will go according to mother's will, if any. If none, then equally to all children. Get a copy of the power of attorney. If you think she is exercising undue influence over mother, or if she is isolating mother from the rest of you, consider either (a) getting a conservator ship, or (b) having that daughter removed.
